So i have good news for those who are using firefox there is this addon that gives you free SMS .
You can download it from:
Its Called World SMS. With it u can send sms to any1. All u need to do is to select ur operator and country then fill out the rest (phone number and the message). Try it out its pretty useful. As far as i know u have unlimited number of SMS to send.
P.S. I hope i posted it in the right section it aint exactly a hack but its a cool tool.
